Application led July 26, 1916. Serial No. 111,448.

. lowing is a full, clear, and exact description thereof.

My invention relates to valves, such as those used for containers for liquids, gases and air in which the internal pressure on the valve is utilied to hold it to its seat, and the object of my invention is to provide a valve of this description which is held normally into contact with its seat and which l may be positively held upon its seat regardless of the effect of any spring mechanism and regardless/of the internal pressure. The device is exceedingly simple, its parts will be few, and its operation may be performed without any special skill or knowledge on the part of the operator, and it is, therefore, well adapted to the 4purpose for which it is intended.

F igure 1 is a vertical section of the valve embodying one form of my invention.

Fig. 2 is a horizontal section of Fig. 1.

In Fig. 1 of the drawing, the valve casing 3 having the hexagonal part 5 shown is of any suitable material and form constructed so that the casing 3 extends from Within the container outward, and having a suitable valve seat 2 preferably integral with the casing and adapted to cooperate With the valve 1 on the inner end of the stem 4 extending through the tubular opening' 4f* of the casing 3 and suitably fastenedat 10 to the washer 9, said washer resting on sleeve 6.

The tubular sleeve 6 is shown having eX- te'rnal screw threads, and adapted to engage the internally screw threaded cap or tap 11, said tap 11 resting' on the upper surface of the hexagonal part 5. The spring 7 is shown in the recessed space 8 with one end resting on the shelf Za of the casing and having the other end in contact with the .expanded nib 4 on the stem 4. Upon the casing 3 is shown the projecting tubular extension 12 upon which is slidably mounted an externally threaded sleeve 6. said sleeve 6 while movable axially or longitudinally, is prevented from rotating or turning as by ilattening or slabbing off the periphery of the block extension 12 and conforming thereto the contiguous surface of the Lore A 'or axial opening through the sleeve 6. The

external threaded sleei'e 6 is employed also in making connections for inflating or filling from pumps or containers.

In Fig. 2 is shown the tubular extension 12, having the flattened side 13 and the conforming side 14: of the sleeve 6 and the tap or cap 11 all in'proper operative relation.

1n the recessed space 8 is shown the spring 7 and the valve stem t suitably placed or positioned.

The action of the device is easily under stood by reference to the drawings, and is as follows It is obvious that whenever the cap 11 is screwed upon the sleeve 6 and the inner end of the cap impinges against the hexagonal piece 5 the sleeve 6 will be moved axially since it is incapable of rotation. l employ this outward movement .of the sleeve 6 to positively move and hold the valve to its seat.

By unscrewing the dust cap 11 it is likewise well understood that movement of the sleeve may occur in the opposite direction and the valve may loe put in yposition for indating or filling by lifting the valve oil? its seat. I employ the spring 7 to keep or maintain the valve'l normally into 'contact with the valve seat 2, and imthis way obA viate the escape of air or any element in case the cap 11 is left of or not fully turned downward.

1. A. valve comprising a casing having an internal valve seat, avalve to coperate with the seat having a valve 'stem extending through a channel longitudinal inthe casing, said channel having a recessed space opposite the valve seat, a spring. in the rean internal valve seat, a valve to. cooperate with the seat having1 a valve stem 'extending through a channel longitudinal to the valve casing, a recessed space in the channel opposite the valve seat, a spring in the recessed space bearing on the valve casing; and the 'valve stem, an externally threaded sleeve on thecasing positioned for axial and not rocessed space hearing on the valve casing and will Htl

tav movemen said sleeve o Jeratvel conl a neoe so he valve Stem, 1th means for 'movnff fmc' hoing the Valve to its seat,

said. embmcing he spring in the re- Cesse space, a threaded member adapted to bear on the valve casing and acting to move the seeve in :m nira direction.

In testimony that I claim the foregoing I have hereunto set my hand.
